We’ve heard or suspected for years that whole foods are healthier for us than processed and ultra-processed foods. But is it true?
The British Medical Journal earlier this year published a study concluding that:
…a higher intake of ultra-processed foods was associated with slightly higher all cause mortality, driven by causes other than cancer and cardiovascular diseases. The associations varied across subgroups of ultra-processed foods, with meat/poultry/seafood based ready-to-eat products showing particularly strong associations with mortality.
You can read the study for yourself free online. Did Big Food (e.g., Archer Daniels Midland, Con-Agra, Monsanto) exert any pressure on the researchers. I dunno.
From the Intro:
Ultra-processed foods are ready-to-eat/heat industrial formulations made mostly or entirely from substances derived from foods, including flavors, colors, texturizers, and other additives, with little if any intact whole food.1Ultra-processed foods, which are typically of low nutritional quality and high energy density, have been dominating the food supply of high income countries, and their consumption is markedly increasing in middle income countries.2 Ultra-processed food consumption accounts for 57% of daily energy intake among adults and 67% among youths in the US according to the National Health and Nutrition Examination Survey (NHANES).34
Ultra-processed foods usually disproportionately contribute added sugars, sodium, saturated fats and trans fats, and refined carbohydrates to the diet together with low fiber.56 As well as having low nutritional quality, ultra-processed foods may contain harmful substances, such as additives and contaminants formed during the processing.
Neurologist Steven Novella wrote a brief post about this study over at Science-Based Medicine. You may also find the comment section there enlightening.
